##是要关闭内核的HWECC和SOFTECC使用yaffs自己的ECC

- uImage (开启yaffs ecc)
附:kernel开启yaffs的ecc校验
1.去掉S3C NAND Hardware ECC 选项
Device Drivers --->
<*> Memory Technology Device (MTD) support --->
<*> NAND Device Support --->
--- NAND Device Support
│ │ [ ] Verify NAND page writes │ │
│ │ [ ] Enable chip ids for obsolete ancient NAND devices │ │
│ │ (0xFF108018) Denali NAND size scratch register address │ │
│ │ < > GPIO NAND Flash driver │ │
│ │ <*> NAND Flash support for S3C SoC │ │
│ │ [] S3C NAND driver debug │ │
│ │ [] S3C NAND Hardware ECC │ │
2.去掉内核的软件ECC校验。
修改内核\drivers\mtd\nand\S3c_nand.c (改NAND_ECC_SOFT -> NAND_ECC_NONE)
1194 nand->ecc.mode = NAND_ECC_NONE;
1195 printk(KERN_INFO "S3C NAND Driver is using software ECC.\n");
3.选择yaffs2自己的ECC校验算法。
File systems --->
[*] Miscellaneous filesystems --->
<*> YAFFS2 file system support │ │
-*- 512 byte / page devices │ │
[ ] Use older-style on-NAND data format with pageStatus byt│ │
[*] Lets Yaffs do its own ECC │ │
[ ] Use the same ecc byte order as Steven Hill's nand_e│ │
-*- 2048 byte (or larger) / page devices │ │
[*] Autoselect yaffs2 format
配置好内核以后重新编译内核。
